SP3222ECA-L

The SP3222ECA-L is a single-channel RS-485 transceiver IC that is ideal for connecting data communication equipment in two-wire bus applications. The SP3222ECA-L is designed to interface microprocessors and controllers to RS-485 buses. It also has high common mode noise immunity, low EMI and spread spectrum transmission. It provides a complete bi-directional communication interface, including data output enable and receive data input enable. It isthus suitable for applications ranging from low-power level to high-speed links.

The SP3222ECA-L is a single-channel RS-485 transceiver IC designed for DTE or DCE applications in 2-wire bus environments. It features low current consumption, high common mode noise immunity, low EMI and spread spectrum transmission. It is packaged in a small, low-profile SOP package and includes an onboard 25 Ω termination resistor between the transmit/receive pins. In addition, it features an internal programmable slope control that limits the rate of transmitter rise and fall times to reduce EMI emissions, allowing it to be used in environments with high EMI levels.

To ensure reliable data communications, the SP3222ECA-L incorporates several different signalling levels such as Data Input Enable (DE) and Data Output Enable (OE). This functionality provides additional control and flexibility when used in point-to-point applications. The DE level is used to enable or disable the transmitter, while the OE level is used to enable or disable the receiver.

Moreover, the SP3222ECA-L supports the standard differential RS-485 signalling protocol, which provides an extended common-mode range of -7V to +12V. This means that the SP3222ECA-L can be used in a variety of applications, from low-power applications to high-speed links. It also provides an under-voltage lockout (UVLO) and an internal reset circuitry which provides a level of protection against voltage transient conditions.

The SP3222ECA-L is particularly suitable for low power and low EMI applications. It features low power consumption, a low dropout voltage and a low standby current. In addition, it features spread spectrum transmission which helps reduce EMI emissions. The device also includes an integrated 25 Ω termination resistor which eliminates the need for external components.

In summary, the SP3222ECA-L is a versatile and reliable transceiver IC that is ideal for a variety of applications. It features low power consumption, high common mode noise immunity, low EMI and spread spectrum transmission. It is suitable for DTE or DCE applications in two-wire bus environments, and supports the standard differential RS-485 signalling protocol. Additionally, the integrated termination resistor eliminates the need for external components, making it a cost-effective solution.
